Filing with gnus-folder REQUIRES (ding) 0.50 OR HIGHER
;;;
;;; To use this
feature, you need to put this file somewhere in your
;;; load-path and add
the following lines of code to your .gnus file:
;;;
;;; (require 'gnus-bbdb)
;;; (setq nnmail-split-methods 'gnus-bbdb-split-method)
;;;
;;; You should
also examine the variables defvar'd below and customize
;;; them to your
taste. They're listed roughly in descending likelihood
;;; of your wanting
to change them. Once that is done, you need to add
;;; filing information to
your BBDB. There are two fields of interest:
;;;
;;; 1. gnus-private. This
field contains the name of the group in which
;;; mail to you from any of
the addresses associated with this record
;;; will be filed. Also, any
self-copies of mail you send any of the
;;; same addresses will be filed
here.
;;; 2. gnus-public. This field is used to keep mail from mailing lists
;;; out of the private mailboxes. It should be added to a record for
;;; the
list submission address, and is formatted as follows:
;;; "group regexp" ;;;
where group is where mail from the list should be filed, and
;;; regexp is a
regular expression which is checked against the
;;; envelope sender (from
the From_ header) to verify that this is
;;; the copy which came from the
list. For example, the entry for
;;; the ding mailing list might be: ;;;
"mail.emacs.ding ding-request@ifi.uio.no"
;;; Yes, the second part *is* a
regexp, so those dots may match
;;; something other than dots. Sue me. ;;;
;;; Note that you can also specify a gnus-private field for mailing list ;;;
addresses, in which case self-copies of mail you send to the list
;;; will
be filed there. Also, the field names can be changed below if
;;; the
defaults aren't hip enough for you. Lastly, if you specify a ;;;
gnus-private field for your *own* BBDB record, then all self-copies
;;; of
mail you send will be filed to that group.
;;;
;;; This documentation should
probably be expanded and moved to a
;;; separate file, but it's late, and
*I* know what I'm trying to
;;; say. :) (defvar
